PROBLEM TO BE SOLVED: To inhibit the thermal conduction caused between a high-temperature part and a low-temperature part to a minimum so as to improve the efficiency of a heat exchanger, and manufacture it in a small size at a low cost. SOLUTION: This is a heat exchanger 10 constituted in such a manner that an internal fluid flows in the tubes 12 of a tube bank penetrated orthogonally to fins 11, in such a state that many fins 11 are laminated in spaced relation to each other and arranged in a plurality of rows in the flowing direction of an external fluid. In the cross-sectional view in the flowing direction of the external fluid, a superheating zone 11a and a subcooling zone 11c are arranged in diagonal positions.
